How Isabelle Garcia works

In last month myself and a few friends received a call from Isabelle Garcia Call Centre and they told us that a friend of our's referred us. They told us that they would like to ask us a few questions and while they were asking a lot of personal questions i ask why do they want to know my income a month and my id number and they said it's just for their database then when i was almost finish they told me that i will receive a voucher soon. some of my friends was also promised a voucher and some were offered a free gift. i just think that their selection system sucks as to who receive's a free gift and who receive a voucher at 50% off your first purchase. how can you buy a product you don't know. a sample would be very nice for everyone to receive so you can see how it works. and i am disgusted that their selection process is base on a person's salary and not if you interested in their products. So if you have a high salary you receive a free gift because they thinks you have money to buy lots more and if you have a low salary you receive a 50% voucher because you can't afford it.
